10 year old trailers banned

I had read in another forum, where some people had encountered campgrounds that banned or limited the stay of travel trailers that were over 10 years old.

Has any of our members encountered this....and if so...where?

One of the posters seemed to infer that he had encountered several in Bill's stomping grounds of Arizona.

I did a quick search of some campgrounds in the Phoeniz area and did see the following posted on a site of one of the three I checked.

Important Policies -

RVs over 10 years old may stay no more than two weeks

Does anyone know if these kind of policies are made to discourage the possible riff-raff....or are there some kind of long-term renters laws that might affect a parks ability to evict?

Thoughts?
